Application filed July 27,

To all whom it may concern. V

' Be it'known that 1, JOHN Morr MoRsn, a citizen of the United Statesand a resident of Syracuse, in the county of Onondaga and State of NewYork, have invented a certain newv and useful Spoke-Nipple Wrench, ofwhich the following is a specification. 7 V a This invention has for itsobject a particularly simple, compact and eficlent wrench for turningthe spoke nipples of wire vehicle wheels, bicycle and motorcycle wheels.

Therinvention consists in the novel fea tures and in the combinationsand constructions hereinafter set forth and claimed.

. In describing this invention, reference is had to the accompanyingdrawings in wh ch like characters designate corresponding parts in allthe views.

Figure l is an elevation of a wrench embodying my invention, thecontiguous parts ofthe felloe and wire spokeof a wheel and the nipple,being also shown.

Figures 2 and 3 are central vertical secional views, the felloe beingomitted, Fig.

2 showing the position of the parts before gripping the nipple and Fig.3, after the wrench is tightened on the nipple.

Figure 4 is a vertical sectional view on line H, Fig. 7 the spoke,nipple and felloe This wrench comprises an outer tubular member or body1, and an inner member 2 having a passage for the spoke, and means asjaws 3 for gripping the nipple 4, the inner member being rotatable inthe outer member which has means coacting with the jaws to effect thetightening of the jaws, and both members having lengthwlse spokereceiving slots arranged to be brought into alinement to receive thespoke and nipple before the jaws are tightened and to be out ofalinement when the jaws are tightened on the nipple.

As here illustrated, the inner member comprises a base 5 which threadsinto one end at 6 of the other member, andthe aws 8 are spaced apartprongs pro ectlng from the base 5, the prongs having inclined or conicalfaces 7 at their ends which engage the complemental conical walls at theother end of the body 1 during turning of the inner member into theouter, and tighten the jaws on the nipple 4. 1

' the body or outer member, the slot extending the full length of thebody and opening through both ends thereof and also through theperiphery and bore of the body.

9 is the spoke receiving slot of the inner member, it being formed inthe base 5 thereof and opening through the outer end and peripherythereof and being of such depth as to extend past the axial center lineof the inner and outer members. The slot 9 at its inner end is in linewith the space 10 between the jaws 3. The inner member is provided witha suitable handle 11.

In operation, the space 10 and slot 9 of the inner member are normallyin radial alinement with the slot 8 of the body when the jaws areunclamped, so that the wrench can be placed on a spoke with the nipplebetween the jaws. The outer member is then turned, thus tightening thejaws on the nipple and moving the space 10 and slot 9 of the innermember out of alinement with the slot 8 so that the spoke is completelyenclosed and the wrench held concentric with the spoke. The wrench isthen turned by turning the body and the inner member as a unit about thespoke, the body being formed with a suitable handle as a knurled thispurpose.

What I claim is:

l. A spoke nipple wrench ner and outer members, the inner member havingmeans for engaging the spoke nipple and being rotatable in the outermember, and the outer and inner members having lengthwise spokereceiving slots arranged to come into and out of radial alinecomprisinginment upon turning of the inner member in the outer member,substantially as and for the purpose described.

2. A spoke nipple wrench comprising an outer tubular member and an innerclamping including opposing spaced apart jaws, the outer and innermember having coacting means to clamp the jaws when the inner membermoves axially into the outer member, the outer member having a spokereceiving slot extending lengthwise thereof and opening into the bore ofthe outer member and through the periphery thereof, and the inner memberhaving a lengthwise slot in line with the space between the jaws, theinner member being rotatable in the outer to bring the space between thejaws and the slot alined with such space into and out of alinement with$116 Sl t of the outer men);

box, substantially as and for the purpose specified.

3. A spoke nipple wrench comprising an outer tubular member and an lnnermember including a base threading into onerend of jaws, andiopening intothe bore of the in ner member and through the periphery thereof, thebase of the inner member having a lengthwise slot in the line with thespace between the jaws and arranged to be brought into and out of'radi'al'alinement V with the slot of the outer member substan- .tiallyas and for the purpose set forth.

In testimony whereof, I have hereunto" signed my name, at Syrcause, inthe" county of Onondaga, and State of New York, this 5th day of July,1921.

JOHN MOTT MORSE.
